2.4.2 “RINSE HOLD” button or “NIGHT CYCLE” This function is available for COTTON, SYNTHETICS, DELICATES and WOOL cycles; in certain models, it is combined with the SPIN button. When this option is selected, the appliance will not drain the tub at the end of the final rinse and at the end of the cycle, the LED corresponding to the START/PAUSE button (and, where applicable, the phase indicator LED) will begin to flash to indicate to the user that the water in the tub must be drained. -

2.5 Buttons for washer-dryers 2.5.1 “ELECTRONIC DRYING” It is possible to select three different electronic levels of dryness: one for COTTON and one for SYNTHETICS cycles: Extra dry (cotton) Store dry (cotton) Iron dry (cotton) Store dry (synthetics) The drying time is automatically calculated by the "Fuzzy" logic. The drying phase can be performed either as automatic drying phase (non stop programme), if previously selected together with the washing programme, as well as a separate drying phase. -

5.4 Detergent dispenser Water is ducted into the detergent dispenser by a solenoid valve with one inlet and two or three outlets. Some models are fitted with a second solenoid valve for hot water fill. The same detergent dispenser is used in all models; the only difference lies in the water intake nozzle. -
Page 36: Power Supply To The Motor
5.5 Power supply to the motor The main PCB powers the motor directly via a TRIAC. Reversal of the direction of the motor is effected by two relays that vary the connection between the rotor and the stator. A third relay powers the stator in half- or full-range operation, depending on the spin speed. The speed of the motor is controlled by a signal received from the tachometric generator. -
Page 37: Circulation Pump
5.6 Circulation pump In Jetsystem models, the circulation pump is powered directly by the main PCB via a TRIAC. 5.7 Heating The heating element is powered directly by the main PCB via a relay. As a safety feature, a traditional dual-level pressure switch (anti-boiling 1 and anti-boiling 2) is connected in series to the heating element. -
